Application filed December 2G, 191.9.v Serial No. 346,349. Y

T 0 all whom t may concern Be it known that I, GIOVANNI MONTE, a subject of the King of Italy, residing at Turin, Italy, have invented certain new and useful Improvements in Electric-Heated ThermosiphOn-Radiators, of which the following is a specification.

This invention relates to electrically heated thermosiphon radiators and has for its object a radiator oi' said type for heating rooms in which the water is heated andheld in circulation therein byheat developed by means of electric resistances.

The annexed drawing shows by way of example an embodiment ot this invention and Figure 1 is a side v iew of the improved radiator, Fig'. 2 is a `fragmentary view on an enlarged scale of the heating' device; Fig. 3 shows to a further enlarged scale one oi' the heads of said device; Fig. 4 is a view of the cover encircling the upper end of said device; Fig. 5 is a diagrammatic view of the connections of the electric resistances.

As shown by Fig. 1 the apparatus comprises a radiator of any known and suitable type and shape consisting of end sections 1 and of intermediate sections 1 communicating' with each other at their top and bottom ends. A. tubular casing 2 is connected to one of said end sections 1 bv means of connecting pieces 3 and el opening at the lower and upper ends of said section respectively. i

`Within said tubular casing 2 `(see Fig. 2) are located three metal tubes 5 each inclosing an insulating pipe 6, say of glass, within which is located a resistance 7-7-7 respectively.

Each oit' said metal tubes 5 is tightly connected with the heads 8 8 of tubular casing 2, the upper one of said heads being shown by Fig. 3, by means of a screwthreaded collar 18 adapted to engage a cooperating projection 19 on said head and to also engage a iiange 2O on the tube 5. The glass pipes 6, which at their ends are iiresealed on the resistance, are clamped in the associate tubes 5 by means oi caps 9,'iitting over the ends of the glass pipe and adapted to engage grooves 10 provided on the ends. Said caps are each provided with a cut imparting them the required resiliency for expanding and engaging said grooves 10 as shown by Fig. 3 in which the clamping parts for the left tubel 5 are shown in position while the clamping parts `for the right tube `are shown apart from' each other for sake of illustration.

Suitable covers 13--13 encircle the heads 8-8 and associate parts. l

For feeding water into the radiator a receiver leil is provided at the top of the casing 2, this receiverhaving a depending pipe 15 leading to the lower head 8 of said casing-2; and said head 8 is further provided with an exhaust pipe 16 having suitable closing means as a screw plug 16. The upper head 8 Oi: tube 2 is finally provided with a duct 1T opening into receiver 11ifor the purpose of discharging thereinto the steam produced inl the radiator and casing 2.

"The ends ot resistances T T-7 lead to sockets 12 located in a plate 12 mounted on the cover 13, the lower ends ot said resistances being connected with said sockets by means otl conductors arrangedl within a covering strip or tube 11, and said resistances are interconnected with each other and with said sockets, as shown by Fig. 5 so that by engaging with either of the pairs of sockets an ordinary two-pin plug 22 said resistances may be inserted in the electric circuit in any appropriate manner so as to give rise to the desired heat development. Y

' As shown by Fig. 5, by engaging the plug with sockets l and Il the resistance 4" is inserted in circuit; when the plug is located in sockets II and lll, the resistance Y is inserted and the resistance 7 is inserted in the electric circuit by engaging plug 22 with sockets lll-IV; finally by engaging said plug with sockets IV and V the resistances 7-7-7 are inserted all in series Ain the electric Vcircuit. y

As it is obvious the water iilling up casing 2 is heated by heat development due to the resistance or resista-hoes and rises in said casing, the hot water beingrsupplied through the connecting piece Al tothe radiator sections while the cold water which has reached the lower end oi said sections 01"' the radiator is l'ed to casing'- 2 through the connecting piece B. Thus the water is caused to circulate in continuous manner, the waterl vaporized within said casing being Vcarried by ductl? into receiver 14 and being condensed therein in contact with the cold water coni tained in said'receiver. v The radiator may be mounted on a sup port 21 having wheels or rollers so that the raten-tea tray 17, 1921.`

place.

The construction according to this invention provides a thermosiphon radiator in which the heating device may have the required size without modifying the general shape or outline of the radiator, the same consisting oit a casing mounted parallel with and adjacent to the radiator sections.

This construction has also the advantage that said heating device is independent of the radiator so that it may be used in connection with radiators having different numbers ci sections and also with the usual radiators which are mounted in .the ordinary manner.
